Cartridge for apparatus for chemically analyzing blood and apparatus using the same

An apparatus for analyzing blood chemistry, comprising:

• an apparatus frame having a compartment;
• a cartridge that is inserted into the compartment of the apparatus frame and includes solution bags that contain solutions, a solution valve unit that allows or blocks the flow of the solution, and a blood introducing unit;
• a sensor card that is disposed in the cartridge or in the apparatus frame and measures the concentrations of electrolytes, the partial pressures of gases, the concentrations of metabolites, or the volume ratio of the red blood cells contained in blood supplied through the blood introducing unit;
• a controller that receives signals generated from the sensor card and processes the signals;
• a lever for the blood introducing unit that is fastened by a hinge to the apparatus frame such that the lever for the blood introducing unit rotates about a hinge shaft;
• a power transmitting unit that is provided at the apparatus frame and that opens or closes the blood introducing unit using torque due to an operation of the lever for the blood introducing unit;
• a solution transporting unit that is provided at the apparatus frame and transports the solutions in the solution bags;
• and
• a driving unit;
• wherein each driving unit includes
• a solenoid unit that is controlled by the controller;
• and
• a movable member that moves based on electrical operation of the solenoid unit and that actuates the solution valve unit of the cartridge, the movable member opening or closing a tubing to flow of the solutions;
• wherein the apparatus frame includes a cartridge door having a cartridge door lock that locks the cartridge door to the apparatus frame and a cartridge door lock sensor that senses a locking status of the cartridge door;
• and
• wherein the apparatus frame includes a lever lock that locks the lever for the blood introducing unit and a lever lock sensor that senses a locking status of the lever.
